If f: \R \to\R and g: \R \to\R are two functions defined by f(x)=a x+b(a \\neq0) \\forallx \\in\R and g(x)=c x^{3}+d(c \\neq0) \\forallx \in\R, then (fog)^{-1}(x)=

Correct Answer is : (x−ad−bac)13

(\frac{x-a d+b}{a c})^{\frac{1}{2}}

(\frac{x+a d-b}{a c})^{\frac{1}{3}}

(\frac{x-a d-b}{a c})^{\frac{1}{3}}

(\frac{x+a d+b}{a c})^{\frac{1}{3}}
